Rare-earth solution from ore leach is passed through a solvent-extraction cascade with HDEHP; Y is peeled off between the heavy lanthanides, then precipitated as Y2O3.
Research Elements Y · atomic number 39 Transition metal · period 5, group 3 [Kr] 4d1 5s2 Shells: 2, 8, 18, 9, 2 Valence electrons: 2 in the outer shell (5s2), and 1 in 4d1 Green dots are the outer shell's s and p electrons. Softer green dots are the d electrons of transition metals, and the d and f electrons of lanthanides and actinides: they often take part in bonding, but not always. Grey dots are the core. Ground-state configuration from the NIST Atomic Spectra Database (A. Kramida, Yu. Ralchenko, J. Reader and the NIST ASD Team). Abundance is the mole fraction of the element found as that isotope on Earth; digits in parentheses are the uncertainty in the last digits.
